Ancak, \u00f6zellikle y\u00fcksek trafikli ve performans kritik uygulamalar s\u00f6z konusu oldu\u011funda, bu soyutlamalar\u0131n bazen bir bedeli olabilir. Kendi web \u00e7at\u0131n\u0131z\u0131 “s\u0131f\u0131rdan” in\u015fa etmek, size sadece kodunuz \u00fczerinde tam kontrol sa\u011flamakla kalmaz, ayn\u0131 zamanda sistemin temel \u00e7al\u0131\u015fma prensipleri hakk\u0131nda derinlemesine bir anlay\u0131\u015f kazand\u0131r\u0131r.

Bu yakla\u015f\u0131m, elbette ki daha fazla \u00e7aba ve bilgi gerektirir. A\u011f programlama, e\u015fzamanl\u0131l\u0131k (concurrency), i\u015fletim sistemi etkile\u015fimleri ve HTTP protokol\u00fcn\u00fcn incelikleri gibi konularda bilgi sahibi olman\u0131z gerekir.

    \n
  1. Soket Olu\u015fturma:<\/strong> Sunucu, bir soket (socket()<\/code>) olu\u015fturarak i\u015fletim sistemine bir a\u011f ileti\u015fim kanal\u0131 a\u00e7ma iste\u011fi g\u00f6nderir. Bu, temel bir telefon hatt\u0131 kurulumuna benzer.<\/li>\n
  2. Adres Atama (Binding):<\/strong> Olu\u015fturulan sokete belirli bir IP adresi ve port numaras\u0131 (bind()<\/code>) atan\u0131r. \u00d6rne\u011fin, bir web sunucusu genellikle 80 (HTTP) veya 443 (HTTPS) portunu kullan\u0131r. Bu, sunucunun belirli bir numaradan \u00e7a\u011fr\u0131lar\u0131 bekledi\u011fi anlam\u0131na gelir.<\/li>\n
  3. Dinleme (Listening):<\/strong> Sunucu, atanm\u0131\u015f portu \u00fczerinden gelen ba\u011flant\u0131 isteklerini (listen()<\/code>) dinlemeye ba\u015flar. Bu a\u015famada sunucu pasif bir bekleyi\u015f durumundad\u0131r.<\/li>\n
  4. Ba\u011flant\u0131y\u0131 Kabul Etme (Accepting):<\/strong> Bir istemci sunucuya ba\u011flanmak istedi\u011finde, bir ba\u011flant\u0131 iste\u011fi (SYN paketi) g\u00f6nderir. Sunucu bu iste\u011fi (accept()<\/code>) kabul eder ve istemci ile ileti\u015fimi y\u00f6netecek yeni bir soket olu\u015fturur. Orijinal dinleme soketi ise di\u011fer gelen ba\u011flant\u0131lar\u0131 beklemeye devam eder. Bu yeni soket, istemci ile sunucu aras\u0131nda kurulmu\u015f \u00f6zel bir ileti\u015fim kanal\u0131d\u0131r.<\/li>\n
  5. Veri G\u00f6nderme\/Alma (Sending\/Receiving):<\/strong> Ba\u011flant\u0131 kurulduktan sonra, hem istemci hem de sunucu, bu \u00f6zel soket \u00fczerinden veri (send()<\/code> ve recv()<\/code>) g\u00f6nderebilir ve alabilir. Bu a\u015famada HTTP iste\u011fi ve yan\u0131t\u0131 gibi veriler de\u011fi\u015f toku\u015f edilir.<\/li>\n
  6. Ba\u011flant\u0131y\u0131 Kapatma (Closing):<\/strong> Veri al\u0131\u015fveri\u015fi tamamland\u0131\u011f\u0131nda veya bir hata olu\u015ftu\u011funda, soketler (close()<\/code>) kapat\u0131l\u0131r ve ileti\u015fim kanal\u0131 serbest b\u0131rak\u0131l\u0131r.<\/li>\n<\/ol>\n

Ancak bu temel yap\u0131, ayn\u0131 anda birden fazla istemciyi y\u00f6netmekte yetersiz kal\u0131r.
